I do high-end pro audio. *We have 1 RU amplifiers that produce 10,000
Watts each. *They are decidedly not Class A I certainly wouldn't expect 1RU amps to be a true class A. Even at a 100 Watt into 8 Ohm load. What make is the one you are dealing with, Dave? Are they mosfets in the output stage or something different; the ones I was referring to are those overpriced consumer grade "audio-sucker" monoblocks, and usually weigh at least a 100 lbs and up. Talk about linear power supplies,good heavens... Heat sinks alone are almost as big as my house cast iron steam radiator!
